2-2. Loadcell Connection
The voltage application of this equipment is 10V, and the maximum current is 120mA, to which up to
four 350
Ω loadcells can be connected in parallel.
■
6-wire connection
The loadcell input of the F600AT is a 6-wire (remote sense) connection. 6-wire shielded loadcell cable
should be used and kept separate from AC or other noise generating wire.
Remote sense lines are used to detect and correct variations in excitation voltage over long cable runs.
■
4-wire connection
Connect 3 and 4, and 5 and 6 as shown below. Be sure to connect 4 and 6 on the terminal block with the
accessory jumper lines because if the four-wire type is used when 4 and 6 are open, apparent normal
operation is performed, but large errors are made in actuality.

Notice
The loadcell excitation voltage of the F600AT is 10V. Heating or breakage may occur
unless the loadcells maximum excitation voltage is 10V or more.
